Type reverse osmosis near me and the results are a mix: big-box stores selling systems in a box, review listings, a map of dealers and a few brand franchise pages. If what you want is someone local to install, service or repair an RO system in your home, this page is for you. You give your ZIP code; your request goes to an independent RO pro who works in your area.

Reverse Osmosis Company is an independent referral service, not an installer or plumber. When you send the form, your details go to an independent local water treatment pro who can contact you and prepare a quote.
How a request finds a pro near you
- You fill in the form: your name, phone, ZIP code and what you need.
- Your request reaches this site’s operator.
- The operator passes it to an independent RO pro who works in your area.
- That pro can contact you about your water, your sink and the job.
- Any quote is yours to accept or turn down.
There is no list of cities on this site and no map of coverage, because the ZIP code does the work. The full steps are on how it works.

What near me should mean for an RO system
For an RO system, near me means more than distance. It means someone local for the life of the system:
- Before the install, someone who can look at your water and your sink, not just ship a box.
- On install day, someone who makes the drain connection, fits the faucet and flushes the system properly.
- For upkeep, someone who can change the filters and membrane on the maker’s schedule. See RO maintenance.
- When something goes wrong, someone to contact about a leak, slow flow or a running drain. See RO repair.
A store, a dealer or an independent pro
The places you find through a near-me search sell RO in different ways. None is right for everyone.
| Where | What you get | What to ask |
|---|---|---|
| A home improvement store | A system in a box, to fit yourself or have fitted | Who installs it, and who services it later? |
| A brand dealer or franchise | One maker’s systems, installed and serviced | Which models, and which contaminants are they certified for? |
| An independent water treatment pro or plumber | Systems they choose to fit, installed and serviced | Which systems do you fit, and why that one for my water? |
This site passes requests to independent pros. It sells no system and recommends no brand. Whoever you talk to, the same questions apply.

How to check a local RO pro yourself
Because no pro is named on this site, check the one who can contact you yourself, as you would any contractor.
Licensing where your state requires it
Some states license water treatment work. Texas is a clear example: the Texas Commission on Environmental Quality requires a Water Treatment Specialist license, unless exempt, for anyone who under contract installs, exchanges, connects, maintains or services equipment in public or private water systems in Texas for the analysis and treatment of potable water. Plumbers licensed under the Texas Occupations Code Chapter 1301 are exempt. Work on reverse osmosis and deionization equipment needs a Class III license, or supervision by someone who holds one. Other states set their own rules, so ask the pro which license your state requires and check it with the state agency.
Permits where your city requires them
Many cities require a plumbing permit for a new RO drain connection. Ask whether yours does, and who pulls it.
The system they recommend
NSF/ANSI 58 is the standard for reverse osmosis drinking water treatment systems. The Texas Commission on Environmental Quality’s advice works anywhere: select a unit certified by NSF, Underwriter’s Laboratory or the Water Quality Association to remove the contaminants you are concerned about, and check that the certification covers them.

What the pro may ask when they contact you
- City water or a private well?
- What do you want the system to do: taste, a contaminant on a test, or no more bottled water?
- Is there a system under the sink already?
- What is the sink like: a spare faucet hole, the countertop material, a garbage disposal?
- Do you want RO water at the refrigerator or ice maker too?
- Do you own the home, or rent it?
Having the answers ready makes the conversation short. On city water, have your utility’s yearly water quality report to hand. On a well, have a recent test. The EPA advises testing a private well every year for total coliform bacteria, nitrates, total dissolved solids and pH, using a laboratory certified to do drinking water testing, and notes that the local health department may provide private well testing for free. See reverse osmosis for well water.
Comparing quotes from RO pros near you
If you get more than one quote, compare them on the same points:
| Point | What to compare |
|---|---|
| Certification | Which standard, and which contaminants are listed |
| Water to the drain | Whether the unit is WaterSense labeled (2.3 gallons or less per gallon treated, under the EPA’s WaterSense criteria) or how much it sends |
| Filters | Which ones, whether you can buy them easily, and the maker’s schedule |
| Installation | Faucet, countertop drilling, drain connection, any fridge line |
| Permit | Whether one is needed and who pulls it |
| In writing | Everything above, on the quote |
The EPA says a typical point-of-use RO system generates five gallons or more of reject water for every gallon treated, and some inefficient units up to 10, so two systems at the same sink can use very different amounts of water.
Looking for RO water to buy?
Some people who search reverse osmosis near me want a place to buy or refill purified water by the gallon. This site does not cover refill stations. It is for people who want an RO system at home, installed, serviced or repaired.


If you rent, or live in a building
An RO system means a new faucet, a branch off the cold supply and a connection to the drain. If you rent, ask the owner before anyone drills a countertop or ties into the plumbing, and get the answer in writing. In a condominium or a co-op building, the board or the building’s management may have rules about plumbing work and who may do it. Tell any pro who can contact you who owns the plumbing before they quote.
Why a referral and not a directory
Directories and review sites hand you a list and leave the calling to you. This site works the other way: you send one form, and your request goes to an independent pro who works in your area. You do not have to sort through listings, and you are not signing up for anything. If the first conversation does not suit you, you are free to look elsewhere, and nothing you send here commits you to buy.
What the site does not do is just as plain. It names no pro, rates no pro and makes no promise about any pro’s work. That is why the checks above are worth a few minutes of your time.
Before anyone comes to the house
- Clear the cabinet under the kitchen sink.
- Find the cold water shut-off under the sink and the main shut-off for the house.
- Put your water quality report or well test where you can find it.
- Decide where the RO faucet should go, and whether you want a fridge line.
- Write down your questions about certification, water use, filters and the permit.
What kind of job is yours?
- A new system at the kitchen sink: RO system installation.
- Treated water at every tap: whole-house reverse osmosis.
- Filters or membrane due: RO maintenance.
- Something wrong: RO system repair.
- An office, a cafe or a small business: commercial reverse osmosis.
Whichever it is, the form is the same: name, phone, ZIP code and what you need. Your request goes to an independent RO pro who works in your area.
Questions people ask

Who will contact me?
An independent local water treatment pro. No pro is named on this site, and this site installs nothing itself.
Does it cost anything to ask?
No. Asking is free and you never have to buy. Any price is in the pro’s quote.
Do RO installers need a license?
It depends on the state. In Texas, for example, the TCEQ requires a Water Treatment Specialist license for water treatment work under contract, and work on RO equipment needs a Class III license or supervision by a Class III holder; plumbers licensed under Texas Occupations Code Chapter 1301 are exempt. Ask the pro what your state requires.
Is reverse osmosis water sold in stores?
Some stores sell purified water. This site is about RO systems installed at home, not water to buy.
